Abstract: A pressure transmitter assembly (100) for measuring a process pressure of an industrial process includes a pressure sensor (500) configured to sense the process pressure. A process coupling couples (106) the pressure sensor (500) to the industrial process. In one example configuration, a phase change material (312) carried in the process coupling (106) is configured to reduce heat transfer from the industrial process to the process variable sensor by changing phase in response to heat from the industrial process. In another example configuration, a thermocouple electric cooling element (122) is coupled to the process coupling (106) and configured to conduct heat away from the coupling (106) in response to an applied electric current.

Abstract: A remote seal assembly (100) for a process transmitter (128) includes a seal body (102) containing a cavity (110) sealed by a diaphragm (106). The seal body (102) configured to be mounted to a process element (104) containing a process fluid such that a first side of the diaphragm (106) is exposed to the process fluid. A capillary (112) contains a fill fluid that is in fluid communication with the cavity (110) and a second side of the diaphragm. A coupling (116) has a capillary recess and two cavities (120,122) separated by a second diaphragm (118). The capillary (112) extends through the capillary recess and connects to the coupling (116) such that the fill fluid in the capillary (112) is in fluid communication with one of the two cavities (120, 122) and the second diaphragm (118). A thermally conductive element (402) preferably extends continuously along the capillary from the seal body toward the coupling (116) and into the capillary recess without contacting the coupling (116).
